The Number 30
I am turning 30 in a few weeks, and I'm wondering if the number 30 has any significance in Judaism?

It certainly does!
The Talmud says that 30 is the age when we reach the prime of our energy (Avot 5:21).
Also, royalty is attained through 30 requisites (Avot 6:5).
The lunar month is a few hours less than thirty days.
Also, there are numerous laws attached to the number 30:
A Nazir vow, when not specified for how long, is for 30 days.
A Kohen serving in the Holy Temple should have a haircut every 30 days.
Pidyon HaBen, redemption of the first-born, is after 30 days. (Numbers 18:16)
So happy birthday - and may you fulfill the prime of your energy!
